= '^,;1ication filed January 2, 191.5.

To ZZ whom t may] concern Be it known that l, FERDINAND l/l Klauen,

of San Francisco, California, have invented certain new and usefulimprovements in Turbine Deep-Nell Pumps, whereof the following is a.specification.

My invention. relates to pumps in general, butl more particularly thoseonf the turbine type, usually employed for pumping Water or other liquidin deepI Wells.

'Ilhe objects of the invention are, first, to provide .means forpacking, holdingand removing the pump casing*- 'rom the Well; second, toprovide a sectional rot-ating shaft for the impeller thereof and meansfor holding Ithe sections together; third, to `lreep the shaft inperfect alinement Within the Well casing; fourth, to provide means foroiling the bearings of said shaft and to remove the Waste oil therefrom,aiuhfiithmieans Where-V hy the Weight of the shaft is 'carried by theimpeller when in operation;aand,sixth, to use Ithe Well casing as adischarge pipe.

lll/'ith these objects in View my invention consists in the novel parts,combinations and arrangements eet forth the following specification,particularly pointed out in the claims at the end hereof,- endillustrated in the accompanying two sheets of drawings, forming a partol1 this application, in which- 4 Figure l is avertical central sectionof bhe upper part of a'well easing, also a sec- 'tion of the upperarrangement of my device, particularly showing the sectional impellershfaiit, one of its guide bearings and oiling device, also means forremmfingthe Waste oil and the pump easing.

Fig. 2 is a cross section taken on dotted line a, o of Fig-, lookingdownward;

Fig. 3 is an enlarged detailed view of the pump shaft coupling.

Fig. Il is 'e vtop view of Fig. 3.

Fig. 5 is la sert screw to secure the coupling of the pump shaft..

Fig. 6 is a, vertical central section of the lower end of Fig. l,showing the lower ar Ell rangement of my' device and particularly aplurality of turbine pumps mounted in the Well casing and the method ofholding, packing and retrieving said pumps; and- Fig. 7 is an enlargedsection similar to Specification of letters Patent.

lhe symbol of reference marks the saine part, in Whichever View saidpart may appean v In these figures: l represents the Well x.using which'forms also the discharge of the pump, 2 the end thereof mounted dponthe upper part et' the Well and provided with outlet pipe, 3., securedto the end, 2.. as at fl.,

l/Vithin the Well is the pump casing, 5, which may be arranged, il'desired, in a plurality of sections, as shown in Fig. 6, and 6 is theimpeller therein provided with the sectional driving shaft 7, secured atthe upper end of the Well by means of a central bearing, 8, andhraclret, 9, which are mount ed upon the discharge end of the Wellcasing.

On the driving shaft is acollar, l0, which rests upon a bracket, 9, andsupports the shaft thereon, when in an inoperative posi tion and 1l is apulley secured to the shaft hy which the motive poweris transmitted. i

The sections of the driving shaft are united together by coupling, l2,which forms the holding means and secured tlfiereon by means ol.headless set screws, i3, havinT a square or other shaped aperture fordriving same in position, es shown in 3, and 5.

.Around the driving shaft is a sectional p1pe,lfl, the lower end ofWhich is screwed, or otherwise removably secured, to the een` Eil @lli

tral portion or' the pump casing, as at l5, as

shown in il and 7, and its upper end is secured te afdownwardcone-shaped projec-y tion, 16, of the bearing, 8, shown in Fig 1, andforms the holdingv means for the pump casing.

The number of seetiops of the pipe depend on the deepness of the i rell,or the length den sii-ed, and these sections are secured together bymeans of blocks, 17, and screw threaded sleeves, 18 engaging the endsofthe sections and the blocks andv form at the same time gli guides forthe driving shaft, 7, through.
